The EXC-DiscretePCIe/Dx is a discrete interface board that provides a complete solution for developing and testing discrete voltage-level interfaces.

The EXC-DiscretePCIe/Dx contains control I/O registers that are memory-mapped and may be accessed in real time.
The board supports up to four built-in modules, each module containing 24 programmable I/O discretes that can record or control the external discretes that are connected to it. In addition, the board can record changes in the input discrete with an associated Time Tag via a built-in FIFO. Output discretes are open collector, capable of handling up to 32V with a maximum sink current of 100 mA each.

The user can set each discrete:

• Either as input or output.

• Either to TTL (0 – 5V) or Avionics (0 – 32V) voltage levels on inputs and

• Either enable or disable external debounce on inputs

There is a 4092 Word FIFO (a string of 1023 discrete entries) containing the data and Time Tags.

The EXC-DiscretePCIe/Dx is supplied with C drivers, including source code and  may be used with Exalt, Excalibur’s Analysis and Laboratory Tools, a Windows monitoring application. Mating connectors provided for I/O connection.
